DC Parameters
These parameters are static or average values that may be exceeded during switching
transitions (e.g. output current).
The XC2786X can operate within a wide supply voltage range from 3.0 V to 5.5 V.
However, during operation this supply voltage must remain within 10 percent of the
selected nominal supply voltage. It cannot vary across the full operating voltage range.
Because of the supply voltage restriction and because electrical behavior depends on
the supply voltage, the parameters are specified separately for the upper and the lower
voltage range.
During operation, the supply voltages may only change with a maximum speed of
dV/dt < 1 V/ms.
Leakage current is strongly dependent on the operating temperature and the voltage
level at the respective pin. The maximum values in the following tables apply under worst
case conditions, i.e. maximum temperature and an input level equal to the supply
voltage.
The value for the leakage current in an application can be determined by using the
respective leakage derating formula (see tables) with values from that application.
The pads of the XC2786X are designed to operate in various driver modes. The DC
parameter specifications refer to the current limits in Table 13.

1) An output current above |I_OXnom| may be drawn from up to three pins at the same time.
For any group of 16 neighboring output pins, the total output current in each direction (ΣI_OL and Σ-I_OH) must
remain below 50 mA.
